Kim Kardashian turns 33 years old today but it looks like she won't be celebrating with boy friend Kanye West when she throws a party in Las Vegas on Friday. The Keeping Up with the Kardashians star, who gave birth to daughter North in June, will be charging party goers at TAO nightclub while her rapper boyfriend will be entertaining fans close by at the MGM Grand Garden Arena.

Meanwhile, RadarOnline.com reports that Kanye West has no intention of marrying Kim Kardashian, in spite of Kim being officially divorced from Kris Humphries.

"Kanye is telling friends that he'll never marry Kim," a source close to the singer revealed to Radar. "He has no need or desire to make their relationship official in the eyes of the law."

"He sees marriage as outdated and he's all about embracing the modern and the new. He doesn't feel like he has to marry Kim just because they have a [daughter, Nori] together," added the source, who explains that Kanye prefers the idea of them being "partners."

As for Kim, she appears to be on the same page as Kanye.

"Kim feels like she's been there, done that when it comes to a big, splashy wedding," the source said. "She used to be so much more into the fame game, but now that she's drifting away from the family and trying to do her own thing, she's becoming more adamant about doing things on her own terms and keeping it low-key. It took her a while to learn the value of privacy, and to abandon the idea of another over-the-top wedding, but she's getting there thanks to Kanye's influence."
